Application filed September 17,1914. Serial No. 862,125.

lic known that l, linnen' l. Corn, a citizen of the United States of America, residing et Detroit, in the county of Wayne und State of lvlichigan, have invented certain new and usei'ul Improvements in Vehielo-Checks, of which the following is a speciticution, reference. being had therein to the accompanying drawings.

Vl`he invention relates to vehicle Wheel chocsv :ind comprises 'the novel construction us hereinafter set forth.

in the drawings: Figure l is o central, lon gitudinal section through the chock; Fig." Q is a pion View thereof; l? ig. 3 is n section on line .1r-iv Fig. l; und Fig. al is o. section on line 1j-y Figfl.

lt the particular object ot' the invention to obtain n construction oi' chock that may he toi-ined from s Hat blank of sheet metal and which possesses n high degree of strength and rigidity. To this end vthe hhi'nli is so fastened as to 'forni e central con,- cuve hearing segnicnt Aj and return-bent portions l and B at opposite sides thereof, which extend ohliquely to the supporting hase and substantially perpendicular to the axis of the segment. The portions B und terminate :it their lower ends in outturned innges C and C suitably tured as at D for the engagement of bolts or securing nieans to the iloor.

increase the strength of the structure the sections l' und B are tiered outwardly ir in the segmental hearing to the hase und earch Afashioned in transverse section so as lo torni u truss. i-is shown in lFig. d, the portion ll is centrally 'bowed outward :it lil, und the portions F on opposite sides thereof ure bowed inward, thereby reinforcing and lo Qing each other. The bearing segment A hss its end portions G rounded out-ward so :is toevoid any sharp corner which might impiego against the Wheel tire and to assist in guiding the wheel into the hearing.

Wi th the construction as described the side portions li und ll extend longitudinally in the direction of maximum stress troni the wheel loud applied, to the segment A.. Furthermore, the securing hase flanges C, being located outside of the position of the'segnientel hearing, there will he no tendency 'to tilt the chock or to lift the bolts or securing' devices from their engagement with the base. rThus en exceptionally strong end rigid structure is obtained, and es this is struck up from c liet blank Without complicated bends, the cost of ninnufacture'is low.

lfVhet l claim as my invention is l. A vehicle wheel chock, formed from sheet metal, having a cylindrical concave hearing segment und return-bent portions on opposite sides of seid segment and for the complete length thereof, the edges of said return-bent portions extending suhstnntially et right angles to the exis of the cylindrical concave hearing portion and obliquely to the supporting hase.

2. A vehicle chocli comprising a sheet Y,

tendine' et suhstantiall*r ri ht cnles to the m .Y c:

axis of seid cylindrical concave hearing seg nient and ohliquely to the supporting base, seid return-bent portions being fa shioned in cross-section to produce a rigid hrnee.

Ll. It vehicle wheel chock, comprising :i nieinber formed from sheet metal having n central portion forming e concave hearing segment, return-lient portions on opposite sides thereof and for the complete length thereof, seid return-bent portions flaring outward and the edges thereof extending ohliquely to the plane of the supporting bese, `said return-bent port-.ions being corrugated in cross-section to form rigid braces, und outwardly-extending flanges :it 'the lower ends of said return-bent portions parallel to the bese.

ln testimony whereof l my signature in presence of tno witnesses.
